No Offence bro, Iv'e been looking at their rear bars myself
so just trying to wrap the old sponge around it.
Fitting a rear bar can be such a pain and time consuming, it "should" only be remove & refit.
Could it be, other motives at play maybe, just maybe.
Store you took it to, sells it own brand correct.
And bars fall off in a show room.
Could it be, A bar fell off a display stand in the show room.
